Question

Write each function in standard form. Determine the x-intercepts of the function.

Y=-4(x+2)(x+3)

Answer 1

X Intercept (-2,0), (-3,0) and Standard form y = -4x^2 - 20x - 24

Explanation:

To write a polynomial in standard form, simplify, and then arrange the terms in descending order.

y = ax^2 + bx + c

y = (−4x−8) (x+3)

Expand (−4x−8) (x+3) using the FOIL Method

y = −4x ⋅ x − 4x ⋅ 3 − 8x−8 ⋅ 3

Simplify and combine like terms.

y = −4x^2 − 20x − 24
